The cotton (Gossypium hirsutum L.) crop is a priority sector of agriculture in the Turkestan Region, Kazakhstan. An evaluation of the cotton cultivar Maktaaral-5027’s response took place for nine variants comprising different doses of nitrogen, phosphorus, and potassium under two soil backgrounds (slightly saline and medium saline). The study occurred at the Agricultural Experimental Station of Cotton and Melon Growing, Turkestan, Kazakhstan. Fertilizers used included ammonium nitrate (34%), double superphosphate (45%), and potassium sulfate (51%), which were applied in one step before sowing the cotton crop for deep cultivation. The fertilizer application revealed some patterns in the formation of seed cotton yield. In the variant combining triple doses of nitrogen with double doses of phosphorus and potassium (N150P100K80) under low soil salinity, the seed cotton yield was higher, reaching 6.49 t/ha of raw cotton. On a slightly saline background, nitrogen fertilizers increased the raw cotton yield to 18.3% and 28.8% in variants with double (N100P100K80) and triple (N150P100K80) doses compared with medium doses of phosphorus and potassium.
